Abstract

PNEUMÁTICO COMPORTANDO UMA CAMADA DE ELEMENTOS DE REFORÇO CIRCUNFERENCIAIS. A invenção refere-se a um pneumático compreendendo uma armadura de vértice formada de, pelo menos, duas camadas de vértice de trabalho tendo larguras axiais desiguais, uma camada C de mistura borrachosa sendo disposta entre pelo menos as extremidades das referidas pelo menos duas camadas de vértice de trabalho, e a armadura de vértice comportando pelo menos uma camada de elementos de reforço circunferenciais radialmente disposta entre duas camadas de vértice de trabalho. De acordo com a invenção, a distância d entre a extremidade da camada de trabalho axialmente a mais estreita e a camada de trabalho separada da camada de trabalho axialmente a mais estreita pela camada C de mistura borrachosa é tal que 1,1ø < d < 2,2ø, ø sendo o diâmetro dos elementos de reforço da referida pelo menos uma camada de elementos de reforço circunferenciais e, em um plano meridiano, a espessura da camada C de mistura borrachosa é sensivelmente constante.PNEUMATIC WITH A LAYER OF CIRCUMFERENTIAL STRENGTHENING ELEMENTS. The invention relates to a tire comprising an apex reinforcement formed of at least two working apex layers having unequal axial widths, a layer C of rubbery mixture being disposed between at least the ends of said at least two layers of apex work, and the apex reinforcement comprising at least one layer of circumferential reinforcing elements radially disposed between two apex work layers. According to the invention, the distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by layer C of rubbery mixture is such that 1.1ø < d < 2 ,2ø, ø being the diameter of the reinforcement elements of said at least one layer of circumferential reinforcement elements and, in a meridian plane, the thickness of layer C of rubbery mixture is substantially constant.
